- secure read access (query) for ITS-S application processes,

- secure notifications (upon subscription) to ITS-S application processes

- management access,

- secure registration, de-registration and revocation of ITS-S application processes at LDM

- secure subscription and cancellation of subscriptions of ITS-S application processes,
